Genesee Arch Bridge

The Genesee Arch Bridge (also known as the Portage Viaduct or Portage Bridge) is a steel arch railroad bridge over the Genesee River in Letchworth State Park, Livingston County, New York. It is the third bridge at this location: the original timber bridge burned in 1875 and was replaced by an iron bridge, which lasted until 2017.

The first bridge, a wooden trestle, in 1864

The Erie Railroad Company built a wooden trestle bridge over the Genesee River just above the Upper Falls in the mid-1800s. Construction started on July 1, 1851, and the bridge opened on August 14, 1852.[1] At the time, it was the longest and tallest wooden bridge in the world.[2] In the early morning hours of May 6, 1875, the bridge was destroyed in a tremendous fire. The bridge was a total loss, leaving only the stone bridge abutments.[3]

Immediately after the fire, officials of the Erie Railroad Company moved quickly to replace the wooden bridge with one built of iron and steel. Construction began on June 8, 1875, and the bridge opened for traffic on July 31, 1875. The bridge was 820 feet (250 m) long and 240 feet (73 m) high.[4] This bridge was used until December 10, 2017. Despite the weight restriction, the 400-ton Nickel Plate 765 passed over the bridge with passenger coaches as part of a heritage excursion in August 2015.[5]

Upper Falls with train passing Portage viaduct

Popular local rumor contends that the Portage Bridge was used for a famous scene in the 1986 movie Stand By Me. In reality, the bridge used in the movie is the Lake Britton Bridge in McArthur-Burney Falls Memorial State Park near Redding, California.[6]

Current bridge

On November 29, 2011, Norfolk Southern Railway announced plans to build a new bridge approximately 75 feet (23 m) to the south of the 1875 bridge. Norfolk Southern offered the 1875 bridge to the State of New York, but the State declined it.[7]

A steel arch design for the new bridge, estimated to cost $71 million, was approved in late 2014.[8] Construction started on October 27, 2015.[9] Following the normal seasonal closing of the Portageville entrance for the winter in 2015, it will remain closed until completion of the project, expected to be in 2018.[10][11] By late 2016, surveying work for the foundation of the new bridge was underway.[12] In March 2017, construction of the main arch began.[13]

On December 11, 2017, the first train crossed the new bridge. The last of the 1875 bridge was demolished on the morning of March 20, 2018.[14] Norfolk Southern formally named the new bridge the "Genesee Arch Bridge" on May 24, 2018.[15]
